These two legendary K-pop maknaes made fans reminisce about the 2nd-gen era after uploading their recent dance challenge.

Former Wonder Girls Ahn Sohee X SHINee Taemin Releases 'MOVE' Dance Challenge

Ahn Sohee and SHINee Taemin became a hot topic among K-pop fans following their recent "MOVE" dance challenge!

On August 3, a video of the two stars dancing together to the chorus of Taemin's hit solo track, "MOVE," was posted on Sohee's personal YouTube channel as shorts.

On this day, Taemin wore a jean jacket and wide jeans and showed off his sexy yet elegant dance moves. Along with him, Ahn Sohee who wore a cute green knit vest and brown pants also performed "Move" dance choreography perfectly.

At first, they surprised viewers by boasting "sharp" dance and impressive harmony when they moved both of their hands and feet.

However, their cuteness and quirkiness eventually showed up when Taemin looked at Sohee and suddenly danced to Wonder Girls' hit song, "Tell Me," while still having "MOVE" background music. The female star then acted as if she was surprised and ran away with a smile.

Taemin continued to tease her by following her while still dancing to the hit track's dance steps.

At the end of the video, the phrase "Ahn So-hee X Taemin, Coming Soon" was engraved, raising expectations.

Following the video, there are many fans were shocked about the surprise collaboration of the two iconic maknaes.

In particular, Ahn Sohee debuted as the main dancer and youngest member of Wonder Girls in 2007, while Taemin debuted as the main dancer and maknae of SHINee as well in 2008.

Wonder Girls and SHINee, whose debuts year are one year apart, have been active as second-generation idols. At the time, they were loved by the K-pop industry as the "youngest" stars who dominated fans' hearts with their outstanding talent, skills, and charms despite their young age.

Sohee was best known for her iconic line, "Omona," from the song "Tell Me," while Taemin was loved for his refreshing and pure appearance and dance when they released their signature song, "Noona Neomu Yeppeo (Replay)."

After about 15 years, fans especially Shawols (SHINee fandom) and Wonderfuls (Wonder Girls fandom) are teary-eyed that the "babies" that they used to cheer on before are now full-grown adults who became the "textbooks" and role models for younger idols.

Some of the comments are:

• "I can't believe I saw Ahn Sohee and Taemin together."
• "I hope Ahn Sohee will be on stage again."
• "You two are so cute."
• "The maknaes who debuted in their third year of middle school and ate the music industry...."
• "The eternal maknaes of the second-generation era. Please give the person who planned this a raise."
• "Both of them grew up really well."
• "Main dancers X Visuals X maknaes X introverts supremacy."
